INVENTOR CHRISTOPHER PEARSON, or PHILADELPHIA, PENNsYLVAivIA-Q I fez-saw.

To all whom it may concern Be it known that I, CHRISTOPHER PEARSON, a subject of the King of Great Britain, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania,

have invented certain new and useful Improvements in Shock-Absorbing Devices for Guns, of which the following is a specification. One object of my invention is to provide a shock absorbing device which can be applied r to the butt endsof rifles and guns, and which [will compensate for the shock caused by the discharge of the gun.

Another object is to so construct my improved device that it will in no way inter- I fere with the manipulation of the gun either duringvthe shooting of the gun or when the gun is being used for drill purposes; it being 2 well known that in various exercises during the 'drill the gun must be dropped upon the ground.

I Aifstill further object of my invention is to make'my improved device of a simple and durable construction and so that it canbe 1 readily taken apart for cleaning or repair I 1 pur oses.

These 7 objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference 1 beinghad to the accompanying drawings in which "Figure lis a top plan view showing the butt end of a gun with my improved device r. 'illustrated in connection therewith, and I 7 Q Fig. 2 is a sectional elevation taken on the line 2-2 of Fig. 1.

Referring to the drawing, 3 represents the butt end of a gun which is preferably'made of wood. Two cylindrical cavities 4 and 5 extend into the butt end 3 from the surface 6. These cavities 4 and 5 are lined with metallic bushings 7. Two plungers 8 and 9 fit within the bushings 7 and coiled springs 10 are interposed between the inner ends of the plungers 8 and 9 and the inner ends of the cavities 4 and 5'.

, A sleeve or band 11 surrounds the extreme f; end portion of the butt 3, as clearly shown in Fig. 2, and a cap 12 slidably fits the sleeve 11; The cap 12 is closed at its outer end 13 and a space14 is normally provided between the cap end wand the surface 6 of the butt l Specification of Letters Patent;

Application filed December 17, 1918. Serial No. 267,115.

3. The cap 12 has oppositely disposed longitudinally extending slots 15 and the sleeve 11 has holes 16 of less length than the slots 15. The holes 16 are normally in alinement with the respective slots 15 and resilient hooks 17, which are secured by screws 18 to the butt 3, have heads 19 adapted to pass through the respective holes 16 and slots 15, so as to prevent the cap from sliding entirely off of the sleeve 11.

The butt 3 is provided with cavities 20 in which the hooks 17 are mounted, said hooks being also provided with finger engaging lugs 21 whereby the hooks 17 can be pressed into the cavities 20 to free the heads 19 from the slots 15, when it is desired to remove the cap. I

In the use of my invention, the cap 12 serves as a shoulder engaging member and when the gun is fired, the butt end 3 will move toward the closed end 13 of the cap 12, the springs 10 being compressed to take up the shock. a The slots 15 permit this relative movement between the butt 3 and the cap 12 and the latter will not become loose during the discharge or manipulation of the gun.

.While I have described my invention as taking a particular form, it will be understood that the various parts of my. invention may be changed without departing from the spirit thereof, and hence I do not limit my self to the precise construction set forth; but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A gun having a resiliently pressed shoulder engaging cap slidably mounted on the butt thereof and having slots therein;

and resilient hooks secured to said butt and having heads adapted to project outwardly from said butt into said slots, said butt being recessed to permit the hooks to be depressed from said slots when it is desired to remove said cap; substantially as described.

2. A gun having a resiliently pressed shoulder engaging cap slidably mounted on the butt thereof and having slots therein; resilient hooks secured to said butt and having heads adapted to project into said slots; said hooks being compressible to withdraw the heads from said slots; and a sleeve interposed between said butt and the gap and upon-Which; tihe ewpii adfififigdfid! slide ss'aifl sleeve bei g secured" to tfie bud and Having holes in register with said slots t6 permit" said heads to" paiss cli'erefllireugh subsfiam tially as described.
